  • Fluidized bed coated amidoperoxyacid bleach composition
    Patent number: 5707953
    Abstract: A coated bleach composition for laundering which contains from 1-97 weight percent of an amidoperoxyacid, and 0-98 weight percent of a hydratable amidoperoxyacid compatible material, less than 2.0 weight percent of water, and a coating of 2-30 weight percent of a water-soluble salt applied by spray coating on a fluidized bed, is disclosed.Also disclosed is a process for the coating of an amidoperoxyacid-containing bleach composition characterized by the steps of spraying, at a temperature below the decomposition temperature of the amidoperoxyacid, a sufficient amount of an atomized spray of an aqueous solution of a water-soluble salt onto a fluidized bed of bleach composition containing an amidoperoxyacid to provide 2-30 weight percent of the water-soluble salt to the composition, and drying the coated composition to a water content of less than 2.0 weight percent. The coating of the composition eliminates caking problems encountered with the uncoated composition.
